OSHA standards for electrical equipment and systems cover the exposed and/or operating elements of an electrical installation. This includes components such as lighting equipment, motors, machines, appliances, switches, controls, enclosures, wiring, labeling of wires, splices, arcing parts, markings, disconnecting means, circuits, and working clearances. These elements must be constructed, installed, and maintained to minimize workplace electrical hazards like shock, electrocution, fires, and explosions. OSHA requires that electrical equipment be free from recognized hazards that could cause death or serious harm, that it be tested and certified by approved organizations, and that it be installed and used according to safety-specific design standards and instructions. Guarding live parts to prevent accidental contact, providing appropriate employee training, and conducting regular inspections are also mandated elements of OSHA's electrical safety standards.
